ACE supports the following major features:

* good compression ratio at high speed using large dictionaries

and solid archiving

* fast extraction and updates

* user interface to make archiving more comfortable

* support of long filenames at WINDOWS 95 (tm)

* ACE.EXE works with different languages;

(English, German, Dutch ..)

* interface includes a "second directory" as a target directory

for operations

* creation of multi-volume and self-extracting archives

* two SFX-modules: SFXJR and SFXSR

* supports RAR-, ZIP- and ARJ-archives

* detects archives and shows them marked on screen

* self-check in ACE.EXE to protect against virus-attacks

* works under WIN_95 and DOS with nearly the same performance

* processing of archives with many files (number depends on free

memory)

* encryption of archived files

* addition of recovery records increases probability

of full recovery of damaged archives

* comments for archives and files

2. Required/recommended/known problems

2.1. ACE

ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;

* MS-DOS 3.0 or above

* 80386 with at least 1.5Mb free memory to run the program

* a temporary drive for its operations

* to update solid archives with 1Mb dictionary there

must be additional 2.9Mb free

* enough space at the TEMP drive for temporary files and archives

* an ega/vga-compatible video card

recommended to get best speed and compression ratio:

* 80586 (Pentium or compatible)

* 10 Mb free memory

* fast temporary drive

* disk cache to minimize time spent accessing diskdrive

(integrated in WIN_95)

when using WIN_95:

* no other running programs

Using a 386-DOS-extender, ACE does not run under WINDOWS 3.xx without

EMS or XMS. If you have any problems with that use the pif file

"ace.pif" to start ace.

Running ACE with QEMM v8.03 might cause rare system crashes.

(caused by a bug in this version of QEMM)

There might be also a problem with some programs like UMB_DRV which

we could patch. To get a list of those problematically programs visit

Harald Feldmann's site:

https://www.xs4all.nl/~feldmann

2.2. The senior SFX-module or UNACE

* MS-DOS 3.0 or above

* 8086 or higher

* enough free EMS or XMS memory for the extraction of archives with

dictionaries larger than 256K

2.3. The junior SFX-module

* MS-DOS 3.0 or above

* 8086 or higher

* 320k free memory

A commandline error will produce output of detailed information about

this error.

If you want to extract file to another directory than the current

type "ACE x <archive> <directory>\ <files>".

The file <filelist> may contain a list of files (wildcards allowed).

Each file in this list must be listed on a separate line.

If there is no file specified at all, all files (*.*) will be handled

(use -r to recurse subdirectories).

To move the output to screen and into a file in parallel use

"-out<file>" instead of ">><file>".

ACE, UNACE and the SFX modules can return the following values as result

of an operation:

errorlevel meaning

0 no error; operation was succesful

1 insufficient memory

2 no files specified

3 the specified archive or list file was not found

4 disk full

5 could not open file

6 read error

7 write error

8 invalid command line

9 CRC error

10 other error

11 file already exists

255 user break (Ctrl+C or Ctrl+Break)

3.5. ACE Environment variable

You can use the ACE environment variable to define switches you always

want to be used when using ACE in commandline mode.

Example: adding following to the AUTOEXEC.BAT will cause ACE to recurse

always subdirectories and lock archives:

SET ACE=-r -l

ACE supports source-destination technique. The files of the current

source directory/archive are listed on the left side of the screen.

The destination directory, also called second directory, is mentioned

at the bottom of the right side of the screen. To exchange the source

for the destination you will have to press <tab>.

The fastest way to set the destination equal to the source is <shift+tab>.

Update (Alt+F4), EGA-M. (Alt+F9) and the sorting F-keys Ctrl+F3..F7.

These functions will not be explained in chapter 4.3.2. again.

F1 - Help

displays a short help on ACE

F2 - Add

similar to RAR: adds the selected files to an archive in the

current directory

F3 - View

views the file at the cursor in "text mode";

if an external program has been specified to be called at this

file, this will be called instead of viewing the file

(see 4.5.3. External programs)

F4 - Fresh

freshens the 2nd directory with the files of the first directory

F5 - Copy

copies the selected files to the 2nd directory

it can be used in archives, too; in this case files

will be added or extracted

F6 - Move

copies (or adds/extracts) files and deletes them after a fully

successful operation

F7 - MkDir

creates a new subdirectory

F8 - Delete

deletes selected files/directories

F9 - Option

displays the options window of the program

F10 - Quit

quits ACE

Alt+F1 - Drive

changes the current drive

Alt+F2 - Solid

same like Add (F2); creates solid archive

Alt+F3 - SFX

same like Add (F2); creates self-extracting archive

Alt+F4 - Update

updates the 2nd directory with the files of the first directory

Alt+F5 - MkCopy

this is one of the more complex functions: an archive will be

created in the 2nd (normal) directory and the selected files

will be added to it

Alt+F6 - MkMove

the relation between MkCopy and MkMove is the same as it is

at Copy and Move; after a successful MkCopy the selected files

will be deleted

Alt+F7 - MkArch

creates a new archive in the current directory

Alt+F8 - Repair

creates a new archive "REPAIRED.ACE" and adds all recovered

files from the archive at the cursor

Alt+F9 - EGA-M.

switches EGA/VGA-cards to 50lines mode; as a result more files

can be displayed at the same time

Ctrl+F1 - View ACE.DOC

views the file ACE.DOC if present in the directory where ACE is

started from; can be used as an extended online-help

Ctrl+F3..Ctrl+F7 - Sort order

sets the order of the listed files to

name, extension, time, size or unsorted

At operations like "copy" the selected subdirectories

are always recursed.

This chapter explains only the functions which differ from the functions

available with normal directories. See chapter 4.2.2. for the other ones.

F2 - Extr

extracts the selected files to the current directory

Alt+F2 - Solid

when applied to a non-solid archive, the archive will be

recreated into a solid archive; see chapter 4.3.4. (recreate)

Alt+F3 - SFX

in case the archive is not already self-extracting, it will be

turned into one

Alt+F7 - FilOpt

this will call up the file options window; see chapter 4.3.3.

Alt+F8 - ArcOpt

calls up the archive options window; see chapter 4.3.4.

Alt+F10 - Test

tests the files of the archive for their integrity

4.3.3. File options

The options of the selected files can be changed by pressing <Alt+F7>.

A menu will be opened with "Encrypt" and "Edit file comments".

"Encrypt" lets you enter a password (if there is no general one).

All selected files will be encrypted with this password. If a file is

already encrypted, the old password will loose its validity.

"Edit file comments" reads the comment of the first file in archive

which is selected. You will be able to modify this comment before

ACE writes it to all selected files.

4.3.4. Archive options

ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ

By pressing <Alt+F8> you will get a list with "Recreate", "Lock archive",

"Edit main comment", "Add recovery record", "Add auth. verific." and

"Add SFX-module".

Take note of the following when using "Recreate":

Recreate extracts all files of the current archive to the

temporary directory. After extraction you might be asked whether it is

okay to overwrite an existing archive (the one you just extracted from).

If an error occurs during this stage, or if you cancel the process, the

old archive will be gone. Do not panic! The extracted files

in the temporary directory will not be deleted and the archiver will

set the current directory to the temporary one. But you will have to

rebuild the archive yourself. (You may use "add" for this).

When recreating a multi-volume archive to a normal archive the volumes

won't be deleted. You have to do this yourself.

"Lock archive" provides protection against further modifications of the

archive. No add of files, add of comments etc. will be allowed any more.

"Edit main comment" reads the comment of the archive. You will have the

possibility to modify the comment before it is written back to the

archive.

"Add recovery record" - see chapter 10. Repair

"Add auth. verific." - see chapter 11. Authenticity verification

"Add SFX-module" - the archive will be made self-extracting;

result is the same when pressing <Alt+F3>

There are several hotkeys you have to know about.

Alt+C - Switch colour mode

toggles colour on/off

Alt+D - Select dictionary size

displays window to choose dictionary for compression

Alt+J - DOS shell

runs the operating system command interpreter

(usually COMMAND.COM)

Alt+M - Select compression level

see chapter 6. for the function of the compression level

Alt+S - Save setup

saves the current adjustments of the program

Alt+T - Set temporary directory

asks for a new temporary directory

There are also keys to select a group of files. These are:

Insert/Space - selects file at cursor

"+" - selects group of file by specified string

"-" - unselects group of file by specified string

"*" - reverses selection

To verify proper operation of the software during compression and

decompression, activate the option "CRC-check after add". If an error

is detected, source files won't be deleted (at move operation), but the

old archive won't be restored either.

Archives are generally uncompressible. To save time during compression,

switch on "Store archives". This will store all ACE, RAR, ZIP, ARJ, LHA

and LHZ files automatically when detected.

Enable the option "Use current password" to avoid the question

"Extract: Use current password?". With "View comments" you may

choose not to display file and archive comments.

"Command line log file" declares a log file which is used as a default

when running ACE in commandline mode. This saves space at the parameter

list.

An explanation of the meaning of the other options can be found at

these chapters:

"Make always solid",

"Dictionary",

"Level" - 6. Compression ratio, time and memory

"Add recovery record" - 10. Repair

"Default comment file" - 8. Comments

"Encrypt files" - 7. Encryption

"Add auth verific" - 11. Authenticity verification

ACE can detect archives by extension or by file content. Detection by

extension is much faster than detection by file content, but does not

detect self-extracting archives. If you don't like this option at all

choose "No detection".

The detected archives can be displayed in different ways.

"Highlight archives" highlights them from the other files listed in the

file list. Switching on "Arrange archives" will list all archives

between subdirectories and the other files. "Archive information" will

display archive information if the cursor is placed on the archive name

for a short moment and the archive is being identified as such.

The sort criterion for the file list in the shell here, too.

(you may use Ctrl+F3..Ctrl+F7)

You can switch between colour and black-and-white mode by the colour

option or by pressing Alt+C. The EGA-mode (43/50 lines) - which offers

to display more files at once on the screen - can also be set by Alt+F9.

Below all the buttons the full information of a specification is dis-

played. As an example, the first button is selected. So the information

box tells us, that whenever the file cursor of the shell is at a EXE or

COM file and F3 is pressed, "%s" will be executed. %s is the file which

was selected when the key has been pressed. So if the user presses F3 at

an EXE file, this file will be executed.

The default F3-definition for LZH and LHA files is "LHA l %s". Means

that LHA will be called (if it can be found on disk) to list the

contents of the selected archive. To call batch files, you have to use

sth. like "COMMAND.COM /C %s" or "COMMAND.COM /C test.bat %s".

(first can call selected batch files, second a certain batch file

with selected file as parameter)

5. Archive creation: archive options

Every time a new archive has to be created within the GUI, you will be

asked for the archive options.

You can set the dictionary size, the volume size and the basic options

the archive will be created with.

An explanation of the options can be found at these chapters:

"Solid", "Dictionary" - 6. Compression ratio, time and memory

"Encrypted" - 7. Encryption

"Recovery rec" - 10. Repair

"Auth verific" - 11. Authenticity verification

"Main comment" - 8. Comments

"Volume size" - 9. Multi-volume archives

6. Compression ratio, time and memory

There are several options that improve compression. Some affect the

memory requirements, others affect the time needed to compress or

update.

"Solid archiving" takes advantage of the fact that all files in an

archive can be viewed as one continuous stream of data. When updating

(adding or deleting) such an archive, ACE needs to re-read all

previously compressed data in order to maintain that continuous

stream since any file added or removed will have to be, or has been,

part of it. Solid archiving is therefore a more time consuming process

than regular archiving. The benefit of solid archiving is stronger

compression of your data.

You should not use solid archives when a large archive requires

frequent updates and time is an essential factor.

Note that solid archiving does not slow down extraction of the whole

archive when compared to non-solid archives.

The best way to increase compression is to increase the dictionary size.

This will also increase the memory requirements at compression and

decompression.

Please bear in mind that the full version of ACE requires a 386+ CPU

and a 32-bit DPMI host. UNACE and the SFX module do not have this

limitation. When uncompressing you will need enough memory to build the

dictionary used during compression. That means if you used a 1024 Kb

dictionary during compression, you will need this same dictionary

during uncompression. Your target machine must be able to provide this

much EMS or XMS memory. When using 256 Kb dictionaries, conventional

memory may be enough.

The limit of SFXSR for dictionary size in conventional memory is 512 Kb,

but few machines will have enough free memory to accommodate this size.

The dictionary size of SFXJR-archives is limited to 256K anyway.

Compression level has no effect on memory use. It is an algorithm

optimization and thus affects only time. The default compression level

is a compromise between time and ratio. If there is a need for better

compression, like compressing for use on the internet, set the

compression level to "good".

7. Encryption

ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ

You are able to encrypt archived files to protect your sensitive

data against unauthorized access. This program does not use RSA so

it may be distributed in the United States of America.

Encryption can be added while compressing or afterwards. To encrypt

files being added to an existing archive, set the password at the

main screen, if you are creating a new archive, you may also set

the password in the archive options window.

To encrypt after compression, enter the archive and press <Alt+F7>.

Choose "Encrypt" from the appearing file options window (see chapter

4.3.3.). Only the selected files will be encrypted.

In order to process files in a solid archive, you need to enter the

correct passwords for each of these files since they have to be ana-

lyzed for processes.

When adding to an archive the compression password will be set to the

general password, which can be set at the main screen. The same applies

to the decompression password during extraction. Changing the

compression password in the archive option window or changing the

decompression password at requests will not affect the general one.

On the command line you can set the general password by using the

"p"-switch.

To protect against hackers passwords are not saved in archives or in

the configuration file. You will have to keep them in your mind.

The author of this program is not able to recover lost passwords!

For security you should choose a long password which nobody except you

knows or can find out. The program distinguishes between upper and

lower case, the maximum length of a password is 56 characters.

8. Comments

ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;

There are two types of comments: the archive comment and the file

comment. The archive comment is displayed during every extraction from

the archive. The file comment, which is linked to a specific file in

the archive, is only displayed when that file is being extracted.

If you wish to use the content of a file as main comment: declare a

"default comment file". This can be done at the main screen or at the

commandline by using the "z"-switch (3.3. Switches). The file will be

used as a main comment for each archive that will be created.

Another way is to input the comment when creating a new archive. Set

the option "Main comment" at the archive options (5. Archive creation:

archive options).

The file comments have to be added after the adding of the files. Use

the file options window (4.3.3. FILE OPTIONS) or the "cf"-command to

comment the selected files.

The main comment can be modified later, too. See 4.3.4. Archive options

and the "cm"-command (3.2. Commands).

The maximum size of the comments is 32 Kb. Due to the screen resolution

the maximum size of the comments entered manually is 4Kb.

9. Multi-volume archives

ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄ

To span a large archive over several disks you will have to split the

archive. The best way to do this is to create "multi-volume" archives.

Handling multi-volume archives is nearly as easy as handling "normal"

archives. A disadvantage of multi-volume archives is that ACE has

no possibility to add to them. Once created the archive can't be

modified.

To create a multi-volume archive you have to set a volume size at the

archive options window:

Volume size ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5407;

( ) none ( ) 1.2 M

( ) Autodetect (*) 1.44 M

K ( ) 2.88 M

The autodetection feature creates volumes according to the space on the

destination disk. The minimum of the size is 65Kb. If there is not

enough space to save the archive you will be asked to change the

destination.

Before a new volume is created ACE will prompt you to change the

destination. This helps to create archives directly onto floppy disks.

The volumes are named this way:

<archive>.ACE, <archive>.C00, <archive>.C01 .. <archive>.C99,

<archive>.100 .. <archive>.999.

So the limit is 1001 volumes per archive.

To decompress a file of a solid multi-volume archive ACE needs all

previous volumes. So be careful with your volumes!

Use this function to recover the files of a damaged archive. It is

activated by pressing <Alt+F8> (chapter 4.2.2.) in the shell or by

using the "r"-command in commandline mode.

Above all solid archives are very susceptible to damages. To lower the

risk you should add recovery records to your important archives.

Such a record contains data about the whole archive to replace damaged

sectors. The record size depends on the archive size:

archive size ?..64K 64K..512K 512K..1024K 1024K..?

record size 1K 2K 4K 8K

The size increase is small, but the safety increase is a lot.

You should enable "add recovery record".

If a damaged archive does not contain a recovery record or if the

archive is too damaged to restore it, ACE will scan for files in the

archive. Because it is unlikely that the whole archive will be

recovered by this, corrupted files are likely to be produced during

extraction.

11. Authenticity verification

This feature is available in the registered version only. By

registering ACE you are able to provide archives with your personal

sign. You must add authenticity verification when distributing an

ACE-archive in a commercial setting.

AV does not only provide users with background information on the

archive, it may also contain a copyright message for its contents.

See chapter 18. Registration for information how to register ACE and

to get an authenticity verification-string.

12. The SFX-modules/UNACE

ﾄﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ 10510c224k 5412;ﾄﾄ

A self-extracting archive contains a small executable, called

SFX-module. This makes extraction without an extra program possible.

ACE provides two SFX-modules - a junior and a senior one. The junior

SFX-module(SFXJR) is much smaller (3.9K) than the senior SFX-module

(SFXSR) (23K). But is slower and provides dictionary sizes up to 256K

only. ANSI-comments are not supported by the SFXJR, too.

Since UNACE and the senior SFX-module are almost the same they have

the same possibilities:

* print of authenticity verification and ANSI-comments

* use of EMS or XMS

* decryption

The SFX-modules do not expect any parameters. But optionally you

can specify a destination to extract the files to. They will extract

all files the self-extracting archive contains.

Usage: <senior SFX-archive> [destination directory]

<junior SFX-archive> [destination directory]

UNACE handles all files, too. The only parameters UNACE expects is the

command and an archive:

Usage: UNACE <command> <archive> [destination directory]

where <command> is one of:

e Extract files

l List archive

t Test archive integrity

v List archive (verbose)

x Extract files with full path

ACE is significantly faster than UNACE or the SFX-modules in

decompressing large archives.

14. Support of non-ACE archives

Using the user interface of ACE you can enter RAR, ZIP and ARJ archives.

You may use Extr(F2), Copy(extraction), View, Test, Delete, Repair and

MkACE(Alt+F2) on these archives. MKACE generates a copy of these

archives in ACE format, the originals will be kept.

ACE uses the most popular programs to realize these operations.

These are:

RAR - RAR.EXE

ZIP - PKZIP.EXE (TEST)

PKUNZIP.EXE (COPY=extraction)

PKZIPFIX.EXE (REPAIR)

ARJ - ARJ.EXE

These programs have to be in the same directory as ACE or the direc-

tories have to be declared in the AUTOEXEC.BAT file in the

PATH-variable (see your DOS-manual).

The author of ACE recommends you use the latest versions of the other

archivers when using ACE archives on non-ACE archives.

15. Support of long filenames (LFNs)

ACE can read long filenames (LFNs) when ran under Windows 95 only

(not under pure DOS 7.00). It will display those names in the shell.

You can adjust the list boundary between the filenames and filesizes

to watch the longer names.

ACE will also store those LFNs in archives. You should be careful

when doing so. If you aim to extract files not under Windows 95

the filenames will have to be converted at extraction.

This conversion is done by all programs send along with this package:

ACE, UNACE, senior SFX-module and junior SFX-module.

Up from ACE 1.1a there will be language or message-files called ACE.MSG.

Those files contain compressed messages of a certain language.

If there is no ACE.MSG, it can not be read, or is damaged, ACE will

use English as default.

The ACE packages will come along with different directories

named by languages. Each of them will contain the specific message file.

You have to copy one to your ACE-directory to use another language.

Since ACE.MSG is compressed, you need some extra files to be able to

translate the messages in there. Please contact me if you like to do so.

20. About me (the author of ACE)

I am born in the year 1979 in Koenigs Wusterhausen, a town near Berlin

(capital of Germany). I grew up in Prieros - a village not far from

Koenigs Wusterhausen.

In 1992 I left the primary school to attend the grammar school. Today

there is my 13th school year (the last one) and my sets are mathematics

and computer science.

My interests are bicycling and other sports as well as reading.

(and from time to time partying ;) )

Up from the 7th school year I learned Pascal from an older mathematician

who used the computer to demonstrate interesting things a better way.

Later I occupied myself with Assembler - in order to write my own fast

graphic routines. At the same time I started experiments in data

compression. So I programmed in two subjects in parallel:

computer animations (3d texturing) and data compression.

When I got to know that no one of my friends has enough engagement to

push up a 3d game (or sth. similiar) and my compressor beat the other

pupular archivers I decided to spend most of my time ACE.

Especially for this I learned C. I also got some expierience

in Visual Labs, Visual Basic and MS Access Basic.

In expectation of the end of my school education I am looking for good

offers regarding to professional training.

Please contact me if you have those or know of other persons who have.

Thank you!
